||Kenneth is accused of the murder of his uncle Marsden and Amy the housekeeper. He flees and falls unconscious in a cave. While he's unconscious, various aspects of his mind--Mr. Memory, Mr. Panic, Mr. Logic, Mr. Alter Ego--review the facts of the case. When Kenneth awakes, he remembers that his uncle's beach chair had been moved to a different spot, and this proves someone else killed him. The murderer is exposed as Marsden's greedy and unfaithful wife.
